I need help with this problem i have in Algebra 1.Here is the instructions: The measure of two angles of a triangle are given. Find the measure of the third angle. Problem:x, y Please help me.
2 ANGLES ARE X AND Y ..LET THIRD ANGLE BE CALLED A
THEN WE HAVE IN A TRIANGLE =SUM OF 3 ANGLES =180.SO
X+Y+A=180
A = 180-X-Y
SINCE WE KNOW X AND Y WE CAN FIND THE THIRD ANGLE A FROM THIS RELATION/EQUATION..
SUPPOSE X= 50 AND Y =70 DEG.THEN
A = 180-50-7-=180-120=60
THIRD ANGLE =60
